Elon seems to be following in the footsteps of many anti-woke-crusaders-turned-conspiracy-theory-nutcases. Most of these people seem to believe that we didn't land on the moon. (e.g. Joe Rogan doesn't, and Matt Walsh got a huge amount of pushback from his fans for saying he did.) But Elon also owns a space company, so he would hopefully be a little more tethered to reality on this point. I think this is an interesting test of whether sufficiently strong evidence can overcome someone's anti-establishment bias.

Any statement from Elon that, in my sole discretion, implies that he believes NASA didn't land a human on the moon as they are generally believed to have done so resolves this YES. Him signal-boosting someone else's claim or implication to this effect also counts. If he claims that smaller parts of the story are faked but the landing did happen (e.g. he claims that the Apollo 13 emergency was fake but the Apollo 11 landing still happened), that is not sufficient to resolve this YES. But if it's ambiguous what specifically he's criticizing NASA for, like he just vaguely insinuates that they faked something, that does count. A claim that they only landed on the moon much later than they claimed to have done so would also count.
